Possibly automatic clothing (4)
I believe the answer is:
gear
This might be a double definition.
'possibly automatic' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'clothing' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for gear that I've seen before include "Toothed wheel, equipment and clothes" , "Equipment; car mechanism" , "Equipment, clothing, goods" , "often changed in a saloon" , "Transmission device - kit" .)
